If you anticipate w hat you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. Th is sect ion will
g ive you some tips on how you can help the envi­
ronment and your pocketbook.
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depend ing upon vehicle load and
speed, road and weather conditions, trip
length, e tc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­ b le -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
.. Try and keep well be low your car's max imum
speed .
Accelerating gently reduces fuel consumpt ion,
engine wear, and does not d isturb the env iron­
ment .
Fue l consumption, exha ust emissions and eng ine
noise increase disproportionately at high speeds.
If you drive at approx imately t hree quarters of
top speed, fuel consumpt ion w ill be reduced by
one half . Never dr ive faste r than the posted
speed limit a nd weather conditions perm it.
Dri ving
Reducing unnecessary idling
Even when your car is just idling it burns up fuel .
.. Shut the eng ine off when you are not driving
the vehicle .
.. Do not warm up the vehicle by lett ing the en-
gine run at idle.
It is efficient to switch off the engine when stop­
ped at ra ilroad crossings and long red lights.
Turning the engine off for just 30-40 seconds
saves more fuel than is b urned by starti ng the
engine aga in .
It takes a long t ime for the engine to warm up
fully when it is ru nning at idle. However, wear
and noxious emissions are espec ia lly hig h when
t h e engine is warming up. So you should d rive
away as soon as you sta rt the eng ine and avoid
run ning at high rpms w hile the eng ine is s till
warmi ng up .
@ Note
Do no t leave eng ine idl ing una ttended afte r
s ta rtin g.
If war ning lig hts s hou ld come on to
i ndica te imprope r operat ion, they would go
u nheede d. Extended idling also produces
heat, which could result in overheat ing or oth­
er damage to the ve hicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your ve hicle serviced at reg ular in tervals.
B y havi ng your ve hicle regu la rly se rv iced by an
Audi dealer he lps to ensu re that it ru ns p rope rly
and economically. The condi tion of your veh icle
not only affects its sa fety and ability to ho ld i ts
val ue, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certai n m ile-
age has been dr iven. ...,

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect d urability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it a lso calls for more concentrat ion from
the dr iver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suitable
for your vehicle and trai ler and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not i nterfere wit h the impact -absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind~,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system .
Safety chains
Always use s afe ty chains be tween your ve hicle
and the tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your Aud i dea le r fo r corr ect w irin g,
swi tches and relays.
Mirrors
If you a re unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
Afte r removing the trailer hit ch, d o no t store
i t in yo ur vehicle. In ca se of sudden br akin g,
the hitch could fly fo rward and inju re you or
your passengers.
Operating instructions
Maximum traile r weight
A trai le r fo r you r vehicle is limited to a typi cal
class 1 or class 2 trai le r.
Trailer load distribution
B e sure the load in the t raile r is held secure ly in
pla ce to p revent it from shift ing forward, back­
ward or sideways .
Never allow a pas senger to ride in a trailer~.&.
in Driving instructions on page 92.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important tha t the cooling system 's pe rform­
ance is up to the additional load. Make s ure that
the coo ling system has enoug h flu id.
Tire pressure
When towing a trailer, inflate the tires of your ve-
hicle to the cold tire pressure listed under "Full
lilJJ..

Trailer mode
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure tra iler safety cha ins are properly connect­
ed from the trailer to the hitch on the vehicle.
L eave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving .
The chains should cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch .
Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obta in the best poss ible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded tra iler when your car itself
is not loaded.
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits .
.. Do not drive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a high ly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as poss ible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
92
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more diff icult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorab le -particularly when
going downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ile rs are lower than fo r regular
vehicles .
Always apply brakes early. When driving down­
hill, shift int o a lo wer gear to use the eng ine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 12 must
be obse rved carefully. The coolant temperature
can increase if you dr ive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on .

fer to. ¢
page 19 .
A WARNING
-
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not proper ly wearing the restraints provided
by Aud i.
Trailer mode notes
Important to know
Your vehicle handles differently when towing a
trai ler because of the additiona l weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful-
ly you load your trailer and operate your r ig. ..,.

Audi drive select (drive
settings)
Introduction
Applies to vehicles: with Audi drive select
Audi drive select makes it possible to experience
different types of vehicle settings in one vehicle.
The driver can select from three
Comfort, Auto
and Dynamic modes using the ~.7l.'i button in the
center console or the MMI to switch between a
sporty and a comfortable driving mode, for ex­
ample . In the
individual* mode, the settings can
be adjusted to your personal preferences . This
makes it possib le to combine settings such as a
sporty engine tun ing with light steering .
.,&. WARNING
Using Audi drive select incorrect ly can lead to
collisions, other accidents and serious inju ­
ries.

· Description
Applies to vehicles: with Audi drive se lect
The vehicle setup in each mode depends on the
vehicle's features. However , the eng ine and steer­
ing are always affected.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission* respond more qu ickly or in a
more balanced manner to accelerator peda l
movements .
Adaptive dampers (Audi magnetic ride)*
The adaptive dampers use sensors to record in ­
format ion regarding steer ing movements, brak­
ing and acce lerat ion operations by the driver,
road surface, dr iv ing speed, and load. With Audi
drive select you can adjust the adaptive dampers
sporty (dynamic), comfortable (comfort) or bal­
anced (auto).
Steering
T he steer ing adapts in terms of steer ing ass is­
tance. There a re diffe rent modes
Q page 113.
Indirect steering that moves easily as in comfort
mode is especia lly suited to long drives on a high ­
way. The dynamic mode provides sporty, direct
steering .
For vehicles with progressive steering* the steer­
ing performance is more agi le .
Cornering light*
The cornering light adjusts when driv ing on
curves at speeds between 6 mph (10 km/h) and
68 mph (110 km/h). The pivoting action and the
lig hting are also adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
Audi drive select mode. Adaptive cruise control
also responds to the driving behavior of the vehi­
cle ahead in a more conservative or sporty man­
ner.

Intelligent Technology
& WARNING
-New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first .
However, you can compensate for the slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en·
danger other road users. This increases the
risk of an accident.
- On steep slopes , reduce the speed and se­
lect a lower gear or lower selector lever po·
sition. Drive as little as possible while press· ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and impair the efficiency of the brakes .
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces·
sarily.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your
ve·
hide can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap·
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im·
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can
remove salt deposits from the brake
rotors and pads by carefully applying the
brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly . Otherwise,
the brake system could overheat, which re·
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis·
126
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
-If the brake booster is not working, you will
have to press much harder on the brake ped·
al to compensate for the lack of the booster .
(D Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nee·
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en·
gine braking effect and relieves the brakes .
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
T he vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing). To steer, you must apply much
more force than usual.
